StackFocus: Macro Camera

StackFocus turns your iPhone into a professional macro camera. At two centimetres from your subject, a single photo can only hold a paper-thin sliver in focus. StackFocus fixes that the way pros do — focus stacking — except the whole pipeline runs on your phone. One tap sweeps the lens through your subject, captures up to 28 frames, aligns them pixel-by-pixel and keeps only the sharpest pixels from every frame. The result: one impossibly sharp macro photograph, exported at full sensor resolution. HOW IT WORKS • One tap — the lens sweeps automatically through your whole subject • Every frame is re-aligned with dense optical flow, so handheld is fine • Only the sharpest pixels survive the stack • Export at true full sensor resolution (48 MP on supported iPhones) BUILT FOR MACRO • Macro lock — the lens never jumps mid-stack • Live focus peaking painted over the viewfinder • Fast / Balanced / Precise modes, metered to the scene • Stability meter for handheld shooting • Keep shooting while your stack processes PRIVATE BY DESIGN • No account. No cloud. No analytics. No networking at all. • Your photos never leave your phone — literally. FREE TO TRY, ONE PRICE FOREVER • Try the complete pipeline free — your first three exports are full-resolution and watermark-free • One $4.99 purchase unlocks everything, forever • No subscription. Ever. StackFocus requires an iPhone with a macro-capable ultra-wide camera (iPhone 13 Pro or later Pro models, iPhone 16 and later).
